Title: Improvements in the transmission of high frequency signal currents over electric power lines
IPC: H04B3/56
Filed: 1928-02-27
Abstract: 286,200. Telefunken Ges. f³r Drahtlose Telegraphie. Feb. 25, 1927. [Convention date]. Wired-wireless systems.-Relates to high-frequency signalling over power-transmission lines, and consists in a method of tuning the feed-lines between the signalling apparatus and the transmission line in such a way as to reduce the load on the high-frequency supply. As shown in Fig. 1 an impedance or tuning-device A is located in close proximity to the condenser C coupling the feed-line l to the power line L. In cases where the feed line is of considerable length, the location of the tuning-device A in this position, relative to the distant signalling-apparatus HF, operates the large loading current which would be created if a long stretch of wire extended between the device A and condnser C. As shown in Fig. 3, a gap in the power-supply lines L1, L2 is bridged by a feed line U conveying signalling currents from the apparatus St, tuning-devices A1, A2 being similarly situated relative to the coupling condensers C1, C2. Choke coils D1, D2 prevent diversion of the signals to earth. Similar chokes may be inserted in the earth lines of the feed wires.

Title: Polyphase alternating current dynamo-electric machines
IPC: H02K17/00
Filed: 1948-02-27
Abstract: 651,750. Dynamo-electric machines. ELLIS, C. E. Feb. 27, 1948, No. 6144. Convention date, Dec. 6, 1945. [Class 35] The stator of a dynamo-electric machine comprises series of skewed rows of pole-faces the poles of each row being energized by alternating current of different phases so as to produce a movement in a conductor depending on the angle of skew. In one form, Fig. 1, described as a squirrel cage induction motor or generator, although it is stated that a wound rotor could be used, the stator 21 is composed of a stack of loose annular laminµ having rows of poles 29 separated by spacers 28. Each pole carries a winding such as 31 which is energized by one phase of a three-phase supply. The poles are skewed from the axial position by means of slats 37 passing through holes in the laminµ and arranged to be moved tantentially by a rotatable ring 40 moved by a worm 42. The result of the skewing is to introduce a peripheral component to the axially moving flux and so cause rotation of the rotor in a direction dependent on the direction of skew. Alternatively the machine can act as a generator whose frequency may be varied independently of the rotor speed. In a modification the skewable poles are interposed between the rotor and a stationary tubular yoke secured inside the frame and energized by annular coils running in grooves around the inner periphery of the yoke. In a further modification, Fig. 6, the rotor consists of a conducting tube divided into axial conductors 68 by slots 69. An outer stator 52 is provided as above, and an inner stator 61, mounted on a fixed tube 59 has teeth corresponding to the rows of poles on the outer stator and is skewed similarly by a slat 64. Both stators are skewed by the rotation of a handle 58 which turns levers 56, 66 fixed to one end of each of the slats. Instead of the mechanical arrangement, the skewing may be done electrically, and Fig. 8 shows the developed diagram of a stator or rotor having a series of rows of poles OV, OW1, OW2, and OW3 with different amounts of skew. These rows are energized at will through a selector switch 75 which may be cam-operated.

Abstract: 1,137,524. Resin bonded laminates. CIBA Ltd. 15 Feb., 1966 [11 March, 1965], No. 6655/66. Heading B5N. [Also in Divisions B2, B8 and C3] Laminates are produced by adhering foamed rubber material to the porous coatings produced by coating textiles with an aqueous preparation containing in an even, fine dispersion: (a) a polymer and (b) microcapsules enclosing a water-insoluble organic liquid, the coating being dried, e.g. at a temperature close upon 100 C., and heat-treated, e.g. at a temperature above 100 C., so that the encapsulated organic liquid bleeds from the capsules and forms pores in the coating. The polymer may be a polymer or copolymer of N-methylol-substituted amides of an α-#-unsaturated monocarboxylic or dicarboxylic acid or of an ether of such a methylolamide obtained by aqueous emulsion polymerization of the monomeric compounds, the polymerization being performed in the presence of a minor amount of a water-soluble alkaline earth metal salt of an α-#-ethylenically unsaturated monocarboxylic acid. The microcapsules may contain a water-insoluble liquid which boils above 100 C., e.g. a mineral oil. The aqueous preparation may also contain an aminoplast used for crosslinking the polymer, e.g. a methylolmelamine highly etherified with methanol. The production of the coating may be combined with a hydrophobization of the textile material which may be performed after the coating operation. The textile material may be a woven or knitted fabric, e.g. of synthetic fibres such as of polyamide, polyester, cellulose acetate, viscose rayon, regenerated cellulose, of natural fibres such as cotton, or of mixed threads or fabrics such as of cotton and polyester. The preparation of the polymer and the microcapsules is described.

Title: Improvements in or relating to gas filled electric incandescent lamps having spirally shaped incandescent elements
IPC: H01K1/50
Filed: 1933-03-07
Abstract: 399,715. Electric incandescent lamps with residual gases. VEREINIGTE GLUHLAMPEN UND ELECTRICITATS AKT.-GES., Ujpest, near Budapest. March 7, 1933, No. 6908. Convention date, April 12, 1932. [Class 39 (ii).] A gas-filled electric incandescent lamp with a spiral shaped incandescent element contains a proportion of dry iodine, either in the form of vapour or in solid form, for example as an iodine compound which is subsequently vaporized within the bulb, for the purpose of preventing internal arc discharges. The iodine may be dried by sublimation of solid iodine, or it may be mixed with phosphorus pentoxide and heated. Dry iodine may be produced within the lamp itself, for example by coating the leading-in wires with an iodine compound from which the vapour is liberated when the lamp is in operation. Preferably a phosphorus iodine compound, such as phosphorus tri-iodide or phosphorus iodide, is employed, thereby producing a drying action in addition to preventing internal arc discharges, so that the usual heating of the lamp during the pumping operation or during sealing off may be dispensed with.

Title: Twisting or coiling wire or like material
IPC: B21F3/00
Filed: 1922-03-10
Abstract: 198,109. Cund, E. March 10, 1922. Coiling; twisting wires together.- In an apparatus for coiling or twisting looped wire or like material, particularly for making swivels for fishing lines, one limb of the wire is axially accommodated in a tubular aperture, and the loop is rotated so as to draw the other limb through an open-ended slot communicating with the aperture, so as to coil it round the first limb. One side of a square or like pillar 1 has attached thereto a fixed link 3 and a pivoted link 4, which is movable towards the fixed link by a cammed handle 15 and may be withdrawn by spring pressure. The inward movement may be limited by a screw-stop 18. Each link has at its upper end a flange 5 which is spaced irom the face of the pillar, and has a slot 7 with a partly closed end 8, so as to form, when the links are assembled, a uniform or slightly tapering bore. The flange on the link 4 has also an open-ended inclined slot 9 and a wire guide bar 10. In order to coil the part 22 of the wire round the body 20, which is carried in the barrel 21 of the swivel, it is first bent as shown in Fig. 4, and the loop 19 is placed over a transverse pin 13 on a handactuated spindle 11. The body 20 of the wire passes through the bore 7 and on closing the link 4, the part 22 is placed in the slot 9 and rests against the guide 10. The part 22 also rests against a spring-pressed guide 17. On rotating the spindle, the part 22 is coiled round the rotating body 20, the spring-pressed guide causing a close coil to be formed. In a modification the wires at both ends of the barrel are coiled simultaneously, the rotating-spindles being geared together and rotated by a single handle. The hand lever for operating the links carries a pair of cam surfaces. Separate pillars are used to support the coiling-mechanism for each wire, one of the pillars being adjustable towards the other.
